湿式静电除尘器可对湿法脱硫之后没有对脱硫工艺生产的细颗粒物进行控制,还有烟尘、PM2.5、SO3、汞及重金属等多种污染物直接从烟囱排出,处于一种自由开放状态。因此,在湿法脱硫装置之后,需要再有一道把关设备,湿式电除尘器成为后处理的理想选择。 

湿式电除尘器能够解决湿法脱硫带来的石膏雨、蓝烟问题,下游烟道、烟囱的腐蚀,节约防腐成本。其性能稳定,可收集微细颗粒物(PM2.5粉尘、SO3酸雾、气溶胶)、重金属(Hg、As、Se、Pb、Cr)、污染物(多环芳烃、二恶英)等,烟尘排放可达10mg/m?甚至5mg/m?以下,实现超低排放,解决烟囱排放问题,达到“一劳永逸”的效果。

由于湿式电除尘器采用水流冲洗,没有振打装置,不会产生二次扬尘。根据相关文献,湿式电除尘器对雾酸、有毒重金属以及PM10,尤其是PM2.5的微细粉尘有良好的脱除效果。所以,可以使用湿式电除尘器来控制电厂的SO3酸雾,同时还具有联合脱除多种污染物的功能。

湿式电除尘器采用液体冲刷集尘极表面来进行清灰,可收集微细颗粒物(PM2.5粉尘、SO3酸雾、气溶胶)、重金属(Hg、As、Se、Pb、Cr)、污染物(多环芳烃、二噁英)等。使用湿式电除尘器后含湿烟气中的烟尘排放可达10mg/m3甚至5mg/m3以下,收尘性能与粉尘特性无关,适用于含湿烟气的处理,尤其适用在电厂、钢厂湿法脱硫之后含尘烟气的处理上,但设备投资费用较高,且需与其它除尘设备配套使用,其投资技术经济性和运行成本要从整体进行评价
